Be it known that l, JAMES CHARLTON, a citizen of the United States, residing in Honston, Harris county, State of Texas, have invented certain new and useful Improvements in Railway-Car Doors and in the Method of Operating the Same; and I do hereby .declare that the following is a full, clear, and exact description of the same.

The invention relates to improvements in hanging and sliding car-doors; and it consists in the construction and novel combination of parts hereinafter described, illustrated in the accompanying drawings, and pointed out in the appended claims.

AIn the accompanying drawings, Figure l represents a side view of a railway-car havi ng a door embodying the invention attached. Fig.2 represents an edge view of the door, showing its side bevels. Fig. 3 represents avert-ical section on the line :c a: of Fig. l.

Referring to the drawings by letter, A designates the side of a railway-car having the sill a extending longitudinally adjacent to the edge of .its floor, and the door-opening a', havingbeveled or inuirdly-converging side edges, and its upper and lower edges, a2 a3, respectively, which are parallel, inclining inward and upward.

B is the car-door, having beveled edges l; and fitting accurately inthe opening a in such manner that the outer and inner surfaces of the door are fiush with those of the car. The door has secured to it near its lower edge and in". its central vertical line a guide-staple, b', for the bolt, hereinafter described.

C is a fulcrum-bracket secured to the door in said line, and preferably a little below the center ofthe door. Upon said bracket is pivoted the operating-lever D, to which is pivoted, a short-distance from the pivotal point thereof, the link-rods d d, the lower ends of which are pivoted to the upper end of thev vertical bolt `E. The said bolt passes through the guide-staple b and enters the keeper e, secured toxthe sill a. It is evidentthatby raising the outer end of the lever D the bolt will be lifted out of its keeper and the door will be unlocked.

f is a link-rod pivoted at its lower end upon the operating-lever D on the same pin that y upper ends, at h, to form,

vcar and can be moved laterall connects the link-rods d therewith, and at its upper end to a crank-arm, f standing from the central part of the transverse shaft F, which is journaled -in bearings in the hanging hinge-joints G. The said joints are composed of the following parts:

' H H are lower hinge-plates secured to the outer surface of the door B by bolts or otherwise at equaidistances from the side edges thereof. The said plates are sleeved at their with the corresponding pintle-pins, h, and the lower sleeved ends, ,of the upper free hinge-plates, I, the hinges proper ofthe car-door. The said plates I are sleeved at their upper ends, e", to form, with the lower sleeved ends, 7', .of theshanger and rider plates J, the joints i',whieh form the bearings for the shaft F,the latter constituting the pintles for said joints j. The said hanger Vand rider platesv have their. upper portions, j2, bent over the'upper edge, k, of the longitudinal Way-beam cured to the side of the car above the door and immediately below the roof. The said upper edge, k, is preferably flat, and the bent over portions of the hanger-plates are then rectangular in eross-section and each provided with opposite bearing-openings L, consisting of the larger circular lower portions, Z, and the smaller circular upper portions, Z', that are the of the anti-friction rollers M, that travel on th'e upper edge ofthe way-beam K. By means of the openings L the door can be lifted from the rollers M till the bent-over parts of the hanger-plates are free of the beam K to dismount the car-door, less in diameter the openings L, should be broken the corresponding side of the door may be lifted, the said roller rcmoved, and a perfect 011e substituted therefor.

It is evident that when the bolt is lifted by the lever D the same lmotion will, on account of the described lconstruction of the hingejointsG and by means of the drawing down of the link-rod f, draw the car-door downward and 'outward till it is clear of the side of the 1-upon the waybeam K in the ordinary well-understood manner.

The mechanism as described is simple.
